I recently used my Netflix in Poland, Japan, Australia, Malaysia and Indonesia. In general, Netflix works everywhere, but as Ronald mentioned the catalogue can differ. Watching via compatible VPN can be a solution if you have fast enough connection.

Also, be aware that language/subtitle options can differ, which can cause hilarious outputs. “Batman vs Superman” was much more digestible with Japanese voices.

Apple TV is a device that connects you to video services (like Netflix) or allows cast from other devices. Are you asking if the device is going to work abroad or your other video services?

In the US we’ve been using Apple TV and accessing our Netflix and Amazon Prime with Apple TV. I saw a mention online that someone was streaming US television, and so I wanted to see if we can do the same when we launch.

I think this is more of a technical issue for you, regarding installing international streaming apps onto your apple TV (which is basically just a mini computer). I would google “watching international television on apple tv” and check out apps you can install onto it, like the Zattoo App.
